The floor heating and air conditioning in Blue Star City have long been stopped due to the lack of diesel power generation, but this protective cave of Blue Star University is very good, surrounded by mountains and forests, and there is a large amount of firewood that can be cut down for heating, so some people come to live here.

When everyone returned to their alma mater, they were very emotional, Wu Yi, Zhou Rong, Ding Tong and others also went to the playground to skate, but because the thick snow on the surface began to loosen, the feeling of skating was not as smooth as before.

When he returned, Ye Tian came to Hunan University and went directly to Xianghe through the path of Hunan University.

The ice in the Xianghe River has been turned up, and there are potholes everywhere, and the ice here does not change particularly obviously.

Mao Ning on the side said:

"Ice is different from thick snow, ice reflects the sun's irradiation, absorbing less heat, plus the entire riverbed is ice, the volume is larger, there is no change for the time being, and the thick snow on land is different, especially those that are attached to the buildings, because the buildings are easy to absorb the sun's heat, and then conductive to the thick snow above, melt faster."

Ye Tian smiled:

"You're really a top student."

Mao Ning said: "This is all junior high school physics knowledge, okay? ”

Ye Tian could only be speechless.

Two days later, Xia Luo and the others gathered together and reported what they had seen, it was true that the thick snow in various places had begun to show signs of loosening, and some places had even begun to melt, but the ice in the entire Xingyue Lake had not changed for the time being.

Ye Tian says:

"Based on the situation of the past two days, we can temporarily draw a basic fact, that is, the temperature in Blue Star is slowly rising, although it is still cold at night and cold during the day, however, there are signs of thawing, and once the thick snow melts, we will encounter some new conditions,

After the temperature rises, the icefish become perishable and cannot be preserved, once the icefish is lost as the main food source, more than 40,000 people in the two cities will face starvation, so, from now on, except for the people who dig the icefish, the rest of the people must all mobilize, and all the icefish that were previously piled up in the river and Xingyue Lake must be transported to the shore, the fish belly will be broken, the internal organs will be dug out, and then hung up to dry and dry.

This work is very important, it is related to our food safety in the future, and when we go back, we must mobilize all people to pay attention to this matter, as well as those stored food, once the weather warms up, there will be a lot

The place will become damp, so be careful to prevent moisture. ”

"A large amount of thick snow melts, the ice water upstream slowly flows down, and when it accumulates to us, there will definitely be floods, our Shashi is in the middle and lower reaches of the Xiang River, fortunately, our current population is relatively small, so everyone should pay attention to finding a safe place to live during this time, and before the flood comes, everyone will move in to temporarily avoid the flood,"

"Once the flood is flooded, it is estimated that it will take at least a month or so based on the current situation, and in this month or so, will my food safety be guaranteed?"

"After the temperature warms, there will be a third new problem, that is, the resources of ice fish can no longer be mined in the future, and we are facing all kinds of alienated monsters on land again, but fortunately, everyone's genetic evolution level has been improved.

How to defend against the invasion of new monsters, and where will we stay then? Is it possible to gather 20,000 people in the city? How to defend, these are questions that everyone has to think about. ”

......

Ye Tian summarized everyone's opinions in the past two days and discussed them with everyone, and the people on the scene put forward a lot of suggestions and methods.

Zhao Gang sighed, "Now it seems that it's still winter, and there are not so many troubles." ”

"What's so good about winter, and you can't wear a skirt, you freeze to death." Zhou Rong said with a smile.

"In summer, there are spotted mosquitoes, and they are all palm-sized spotted mosquitoes, and sucking a mouthful of blood can kill you."

"I miss the smell of roasted mosquitoes."

"Haha, me too, I still miss the taste of frog hot pot, after this hibernation, I haven't seen a frog, now a frog is dozens of catties, you can make a big pot of hot pot, put a handful of chili pepper garlic ginger mother, that taste ....."

"Damn, don't say it, I'm drooling, I can't wait to catch the frog now."

"Haha....."

Everyone is looking forward to the arrival of spring.

Ye Tian temporarily stopped training for ten days, and then everyone went back to lead their respective teams to deal with the matter of the ice fish, and he himself came to the magic capital through the teleportation channel and Mao Ning.

Walking out of the teleportation circle, I saw the World Financial Plaza at a glance, and I inexplicably remembered No. 15 in my mind.

"Mu Mu, I want Mu Mu."

Ye Tian walked towards the gate of the World Financial Plaza, and was immediately stretched out by the four tower guards at the door

Hand Block:

"No entry without permission."

Ye Tian says:

"I want to meet the Tiger Mentor, I wonder if he's here?"

"Mentor Tiger didn't leave an order, saying that someone is visiting today, please go back."

Ye Tian was stunned for a moment and said:

"Can I find waiter number 15 then?"

"No, one last word, please come back, or I'll fight you off."

Ye Tian was helpless, so he had to turn around and retreat, muttering:

"Nima, this tower guard speaks so stiffly, it's like a robot."

Mao Ning on the side said:

"They could be robots."

Ye Tian turned his head to look at Mao Ning.

Mao Ning smiled faintly and said:

"Haven't you looked closely? Each tower guard is the same height, although there are differences in faces, but the expressions of speech are all similar, if it weren't for robots, I can't imagine what kind of people would be so neat, at least, the body and appearance of the shopkeepers of different gene exchanges are very different. ”

Ye Tian listened to this, and suddenly realized that he had always doubted the identity of this tower guard, why didn't he think about the robot.

Ye Tianyi patted his head and said:

"That's right, it's robots, I've observed them before, they stand guard around the clock and never eat, but why do they have such strong combat power? And so responsive? ”

Ye Tian has seen the tower guards kill people with his own eyes, and the last time he trained, someone fought against the tower guards, and everything was the same as a real person.

Mao Ning says:

"This is easy to understand, you have to jump out of the thinking of the Blue Star people, you must know that this alien civilization is highly developed, and the level of science and technology and fantasy civilization are far beyond the limits of human imagination."

Ye Tian nodded, he found that Mao Ning's starting point for thinking about the problem was very high, and the angle was also very novel, it was indeed not a loss that the whole family of the last two generations was the descendant of doctors.

Ye Tian deliberately walked to the thick snow outside the square, stepped on it with his foot, the thick snow on it was a little loose, grabbed a handful with his hand, felt the loose feeling with his own hands, and his heart was bright.

The world is hot and cold, and winter is really coming to an end.

Ye Tian came to Fudan University and found Lin Tianxing.
